The article presents the research results of the effect of AgroMyc microbial drug on the spring barley yield. This microbial drug contains the strains of nitrogen-fixing and phosphate-mobilizing bacteria as well as arbuscular mycorrhizal fungi. It was determined that due to the application of microbial fertilizer the reduction of nitrophosphates that are applied to brewing barley is possible, which is of great importance both ecologically and economically.

The article presents the results of storing the fruits of industrial varieties of apple fruits of the Belarusian selection Darunak, Imant and Nadzeyni. The main storage pathogens, the period of their manifestation and harmfulness are determined, the size of losses in dynamics are determined. The influence of varietal features on the infestation of fruits by certain pathogens has been determined. The Nadzeyni variety has the highest number of fruit losses caused by fruit rot (9.8%) and Darunak and Imant varieties by bitter rot (9.0-9.9%). It is determined that despite the presence of an intensive system of fruit protection during vegetation, the loss of fruits during storage depending on the variety can reach 13.6-22.9%, which negatively affects the efficiency of fruit production.
